General usage information

OpenJDK is an open source implementation of the Java Development Kit (JDK). It includes a Java virtual machine, the Java Class Library, and a java compiler.

The commands java, javac, javadoc, jar, etc. have been added to your path.

In case you need to link against this library in your code, the following environmental variables have been defined:

  • \$OPENBLAS_ROOT has been set to the root of the openjdk installation
  • \$OPENBLAS_LIBDIR points to the directory containing the libraries
  • \$OPENBLAS_INCDIR points to the directory containing the header files

You will probably wish to use these by adding the following flags to your compilation command (e.g. to CFLAGS in your Makefile):

  • -I\$OPENBLAS_INCDIR
and the following flags to your link command (e.g. LDFLAGS in your Makefile):
  • -L\$OPENBLAS_LIBDIR -Wl,-rpath,\$OPENBLAS_LIBDIR
